Keeping your deployments from turning into horror stories

Astro 5.15 lands with skew protection 🎃

Astro 5.15 introduces automatic Netlify skew protection, new adapter APIs, and fine-grained font preloading. Plus, a few handy quality-of-life improvements.

Here’s what’s new in Astro 5.15:

🛡️ Netlify skew protection: Automatically keeps your client and server versions in sync to prevent mismatched deployments and weird runtime bugs.
⚙️ New adapter APIs: Hosting platforms like Netlify and Vercel can now customize headers and asset query parameters for better reliability.
🅰️ Granular font preload filtering: Control exactly which font weights, styles, and subsets get preloaded for faster performance.
🧑‍💻 Stack trace copy button: Quickly share errors with AI tools or teammates for faster debugging.
☁️ Cloudflare wrangler scaffolding: astro add now sets up wrangler.jsonc automatically when adding Cloudflare integrations.
📦 Node 18 deprecation: The Vercel adapter now marks Node.js 18 as deprecated in favor of newer LTS releases.

Add fast, client-side search to Astro 🔍

Static sites are fast and delightful, but adding full-text search can feel impossible, especially if you want to avoid remote APIs or slow crawlers.

This guide shows how to generate a build-time JSON index from your Astro content collections and use client-side libraries to create fast, fuzzy, and accessible search.
